Subject: Re: The shape of a function and its degree

Polynomials of even degree are not parabolas. Polynomials of degree two are. Someone has not figured out how to find the roots of a polynomial of degree greater than four. In fact Galois proved it is impossible. Polynomials do not all have lines of symmetry. I can only assume that what the mis-informed teacher that wrote the note before this one is that they were talking about polynomials of the form y=a x^n.
